Manually delete the cache

After trying it a few times I can’t find any errors popping up. I added *.meta files to be deleted as well.
Here’s my final ssh command:
ssh user@host "find /www/wp-content/cache/ \( -name '*.html' -or -name '*.html.gz' -or -name '*.meta' \) -delete"

For anyone that reads this I switched to an even better solution: moving the cache folder first, then deleting it. Should save you from any PHP collisions.

cd www/wordpress/wp-content
# example folder
mv ./cache ./cache_old && mkdir -p ./cache
# move cache and if moved make new dir
if [ -d ./cache_old ] && [[ "$PWD" =~ www/wordpress/wp-content ]]; then
  # if previous cmd was a success and
  # we're in the right folder
  rm -rf -- cache_old
  # the -- is a safeguard thing when using rm -rf
fi

Could there be a much easier solution for a non technical people. I offer Forex Signals on website which are sent in real time. I noticed that after installed plugin I need to manually clear cache every time I post a signals. Sometimes even after clearing cache it takes 10-15 mins before signals are delivered.

Since the nature of business is time sensitive I’d to uninstall the plugin in order to deliver content in real-time.

wp-super-cache does try and offer options that lets you delete the cache whenever you make new post, a comment is made, or both. Check Settings -> WP-Super-Cache -> Advanced.

Or you could expand when it deleted the cache using add_action, check out this forum-thread.
